Title: Methods and products for facile microbial expression of dna sequences
Inventor: DE BOER HERMAN ALBERT
IPC: C07H21/04
Filed: 1982-09-16
Abstract: Microbial expression of an exogenous polypeptide may be inefficient if the messenger RNA has secondary structure (due to complementarity of spaced regions of the molecule) which impedes interaction with a ribosome. The occurrence of such structure can be predicted. The degeneracy of the genetic code gives freedom to alter the nucleic acid composition of the cDNA to eliminate harmful secondary structure of the mRNA. For example, bovine growth hormone (BGH) is poorly expressed by E. coli transformed with a recombinant plasmid containing the natural BGH gene. The corresponding mRNA has complementary regions at 46-51 and 73-78. Therefore a plasmid pBGH 33-4 was constructed containing a BGH gene whose upstream portion was synthesized (making use of plasmid pHGH 207-1 which contains an efficiently expressible gene for the closely related human growth hormone) so as not to cause the troublesome complementarity. E. coli transformed therewith produced BGH with a yield of better than 10<5> copies per cell.

Title: A beam structure
Inventor: COOK DAVID GEORGE
IPC: B64C3/18
Filed: 1984-04-13
Abstract: An I-beam structure has top and bottom rails 10 and 12 joined by a web 14. The web is loaded in shear when the beam is supporting a load. The web is very thin, as it has been found that, provided the web is held accurately in one plane, the necessary resistance to shear can be achieved with a thin, and therefore light, web. To ensure that the web is held in this way, supports 18 are provided for maintaining the web in the right position. A strong, light-weight web as described finds particular application as the main structural beam in an aircraft wing. It is especially useful in the wing of a microlight aircraft. <IMAGE>
Patent GB-2149324-A (GB)
Title: Compartmentalized centrifugation chamber
Inventor: MARTIN DR HANS
IPC: B04B5/04
Filed: 1984-07-03
Abstract: The stability of buoyant density gradients in centrifuge tubes decreases rapidly when the volume of the tubes is increased beyond 50-100 ml. This is because vortices form in large tubes on acceleration and deceleration of the centrifuge. For large-scale density gradient separation of particles, e.g. biological cells, using centrifuge tubes it is therefore necessary to distribute the material into a number of small tubes. This time consuming procedure is simplified by using a compartmentalized centrifugation chamber, which is subdivided by radially and vertically oriented walls or lamellae into a number of hydrostatically communicating compartments. The walls stabilize the large volume density gradient without interfering with sedimentation of the particles. As the compartments communicate, it is possible to layer and fractionate the density gradient in all compartments simultaneously. This results in a considerable reduction of time and labour required to separate large volumes of material by density gradient centrifugation.
